Product details
Overview
PR3007G-T from Diodes Incorporated is a 3.0A, 1000V peak repetitive reverse voltage fast recovery glass passivated rectifier diode in DO-201AD package, with 150ns reverse recovery time, 1.3V forward voltage at 3.0A, and 5.0μA reverse leakage at 25°C - used in offline AC/DC input stage rectification for industrial power supplies.
For engineers reviewing the PR3007G-T datasheet, PR3007G-T pinout, PR3007G-T application, or PR3007G-T equivalent, key selection criteria include VRRM=1000V, trr=150ns, IO=3.0A @ TA=55°C, RθJA=32°C/W, and DO-201AD mechanical compatibility with high-surge (125A) requirements in mains-fed power conversion.
Technical Context
This device is a single-phase, silicon planar junction fast recovery rectifier optimized for high-efficiency switching power supplies and UPS systems. Its glass passivated die construction ensures stable performance under thermal cycling and humidity stress, while the 150ns trr enables operation up to ~100kHz without excessive switching loss.
The DO-201AD package supports lead-free reflow soldering per MIL-STD-202, Method 208, with cathode band polarity marking and 1.12g mass. Thermal resistance of 32°C/W (junction-to-ambient) requires heatsinking above 1.5A continuous conduction in enclosed environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse line transients up to 1000V in universal-input AC/DC front-ends. |
| IO @ TA=55°C | 3.0 A - Continuous average forward current rating at 55°C ambient, derated linearly to zero at 150°C junction. |
| VFM @ IF=3.0A | 1.3 V - Forward conduction loss of 3.9W at full rated current, directly impacting thermal design and efficiency. |
| trr | 150 ns - Fast recovery minimizes reverse recovery charge (Qrr), reducing EMI and switching losses in flyback and boost PFC stages. |
| IFSM (8.3ms) | 125 A - Handles cold-start inrush and lightning-induced surges without failure in Class I/II AC inputs. |
| IRM @ 25°C | 5.0 μA - Low leakage preserves hold-up capacitance and reduces standby power in no-load conditions. |
| RθJA | 32 °C/W - Requires ≥2.5 cm² copper pour or external heatsink for sustained 3A operation at 55°C ambient. |
Pinout & Package
DO-201AD axial-leaded plastic package with cathode band marking; two-terminal device (anode and cathode) with no internal connections beyond the PN junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must withstand full reverse voltage when reverse-biased. |
| Cathode | Forward current exit point | Marked with band; connects to bulk capacitor positive rail; carries full output current and ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates moisture-induced leakage drift and improves long-term reliability in humid industrial environments. |
| 125A non-repetitive surge rating | Survives EN 61000-4-5 Level 3 (2kV line-earth) surge events without parametric shift or failure. |
| 150ns reverse recovery time | Enables use in 65–100kHz SMPS designs without requiring snubbers or additional loss mitigation. |
| RoHS-compliant tin-plated leads | Compatible with Pb-free reflow profiles (peak 260°C) and meets IPC-J-STD-020C Level 1 moisture sensitivity. |
Applications
| Industrial AC/DC Power Supplies | UPS Input Rectification |
|---|---|
Use Scenario: Mains rectification in 100–500W industrial switch-mode power supplies with universal 85–265VAC input. IC Role / Device Role / Timing Role: Primary-side unidirectional current path converting AC line to pulsating DC before bulk capacitor and PFC stage. Use Value: 1000V VRRM margin accommodates 265VAC × √2 + 20% tolerance = 375V peak, enabling robust overvoltage headroom. |
Use Scenario: Input bridge rectifier in online double-conversion UPS systems handling generator-sourced or distorted grid waveforms. IC Role / Device Role / Timing Role: High-surge-capable rectifier absorbing transient energy during transfer switching and harmonic-rich load cycles. Use Value: 125A IFSM rating sustains 10-cycle 60Hz surges typical of generator start-up and motor load switching. |
| LED Driver Front-End | Motor Drive Auxiliary Supply |
Use Scenario: Off-line LED driver input stage powering constant-current ICs in streetlight and high-bay fixtures. IC Role / Device Role / Timing Role: High-voltage rectifier feeding HV buck/buck-boost controller ICs operating directly from rectified mains. Use Value: 150ns trr limits switching node ringing and EMI generation near sensitive analog dimming circuitry. |
Use Scenario: Auxiliary 24V supply rectification in three-phase inverter drives powering gate drivers and control logic. IC Role / Device Role / Timing Role: Isolated auxiliary rectifier on transformer secondary, delivering low-noise DC to isolated DC/DC converters. Use Value: 5.0μA IRM at 25°C ensures minimal standby drain on auxiliary winding during drive idle states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM=600V, trr=75ns, IO=3.0A, SMD TO-277 package | Limited to 277VAC systems; superior speed but lower voltage margin than PR3007G-T | Select when board space is constrained and 600V rating suffices with tighter trr requirement |
| VS-3EYH02-M3/54 | VRRM=1000V, trr=200ns, IO=3.0A, DO-201AD, higher IRM (50μA) | Higher leakage degrades light-load efficiency; same package and voltage rating | Acceptable where cost is primary concern and leakage-sensitive circuits are absent |
Compared with STTH3L06S and VS-3EYH02-M3/54, PR3007G-T uniquely balances 1000V robustness, 150ns speed, and 5μA leakage - making it optimal for universal-input industrial power where voltage margin and low standby loss are both critical.

FAQ
Is PR3007G-T suitable for use in automotive applications?
No. PR3007G-T is not AEC-Q101 qualified and lacks automotive-grade screening, temperature range validation (-40°C to +125°C), or PPAP documentation. It is specified for industrial and commercial power supplies only, with operating range of -65°C to +150°C and no guaranteed performance under automotive vibration or chemical exposure.
What is the maximum PCB pad size recommended for DO-201AD thermal relief?
For optimal thermal performance, Diodes recommends ≥2.5 cm² of 2-oz copper connected to each lead (anode and cathode) with at least four thermal spokes. The 32°C/W RθJA rating assumes this layout; smaller pads increase junction temperature by up to 20°C at 3A continuous load.
Does PR3007G-T require a snubber circuit in 100kHz flyback designs?
A snubber is not required for basic operation due to its 150ns trr and low Qrr, but may be needed if layout parasitics cause >50V overshoot at the switching node. Measured trr was tested at IF=0.5A/IR=1A/Irr=0.25A - actual recovery behavior depends on circuit dI/dt and stray inductance.
Can PR3007G-T replace PR3006G in an existing design?
Yes, with full functional compatibility: both share identical DO-201AD package, 3.0A IO rating, 125A IFSM, and 150ns trr. The only difference is VRRM - PR3006G is rated at 800V versus 1000V for PR3007G-T - so replacement is safe if system peak reverse voltage remains ≤800V.
